E.g. If I need to bring two divers from 50m to 6m from the end of the bottom portion because that's where my next gas is (oxygen) as I've planned to do that based on an (extremely shallow) "optimal" algorithm, it's a logistical issue.
I'd prefer nitrox 50, which I can deploy at 21m. Example of less bottom gas requirement.
E.g. If my buddy and I are diving, I'm on O/C and he on CCR, our gasses and asend profiles become identical, even if he bails out (maintaing a pp02=1.2 average on O/C). Example of system interoperability.
E.g. If I'm on deck and dive site A is out, I can skim our gear and gas, and have a new dive plan ready within 10 seconds. Example of ease of planning.
E.g. If I'm on the deepest part of a wreck and find life sucks there, I can adjust my plan and know exactly what I can do with the gas available to me if I hop up to the shallower portion, before I do so. Example of ease of adjustment.
E.g. If I'm teaching a team and I want to develop or control their level of awareness, I can see if/how they adjust their deco time based on various stimuli. Example of value as a training tool.
None of those examples require a deep stops approach. Not one.
